| 1. | The sample with low emitter efficiency has completed as the method of above . this lead to the greatly decrease of the reverse recovery time and the low reverse leakage and forward voltage , especially the excellent temperature character of the leakage . the test date shows that the samples reach the first class of international level 本论文作者通过仿真测试,验证了课题研究的理论设想,并设计制作了具有低阳极发射效率结构的高压功率frd ,利用局域铂掺杂和电子辐照相结合的寿命控制方式,实现器件反向恢复时间的极大减小,并且反向漏电流、软度因子、正向压降等关键参数也较理想,且具有极佳的漏电温度特性,达到器件综合性能的优良折衷,达到国际先进水平。 |
